Picasa 3.x message – unfinished operations

I had a little snafu with Picasa today. I got a message that said that there were unfinished operations do I really want to close. Ofcouse, I got this when I was trying to close it. It turns out that it means that I had tabs open up top in Picasa and it wanted me to close them. In this instance it happened to be the import tab.
